Someone was stating that they couldn't see how the LT25 would be a better trainer than the LT40. I trained on an LT40 and my son won an LT25 at one of our club meetings. The LT40 is a great trainer and will land at very slow speeds. I found out however that when the wind suddenly got really gusty, the LT40 had a real problem penetrating the wind and almost stopped moving forward. This is pretty fast winds we are talking out here! We landed in a few minutes out of frustration and then put the LT25 in the air. The LT25 penetrated easily, was easily controllable. It didn't ballon in the turns and and was actually a blast to fly. We put the LT40 up for sale after seeing this and kept the LT25!
